feat(notifications): include berth-range suffix in stage-change titles

Stage-change notification titles previously read "Acme Corp moved to
Reservation" with no context on which berths the deal covers. For
multi-berth deals the rep had to drill into the interest to see what
moved. With multiple deals in flight per client the bell tray became
ambiguous.

Switch the title-build path from `getPrimaryBerth` (single-row) to
`listBerthsForInterest` (full set) and append a compact suffix via
`formatBerthRange()`:

    Acme Corp moved to Reservation [A1-A3, B5]

Falls back to plain "<subject> moved to <stage>" when the interest
has no linked berths.
